It participates in the constitution of chlorophyll with an effect on the photosynthetic process and contribution to energy metabolism, helps the absorption of phosphorus and participates in the formation of carbohydrates in the plant.
Deficiency – It starts in the older leaves, with yellowing between the veins, which differs from nitrogen deficiency.
It reduces the rate of photosynthesis, which leads to low plant growth and impacts on productivity. It usually appears at fruit maturation when the plant has a high pending load.
